Abstract

La présente invention concerne un dispositif de gestion d'énergie qui comprend : une unité de gestion qui gère au moins deux installations raccordées à un système d'alimentation ; et une unité de commande qui commande une alimentation électrique distribuée installée dans chacune des deux, ou plus, installations. L'unité de commande applique une première commande à une première alimentation électrique distribuée installée dans un premier groupe d'installations dans lequel un flux d'énergie inverse vers le système d'alimentation est autorisé et qui comprend une ou plusieurs installations dans lesquelles le flux d'énergie inverse n'est pas supposé, et applique une seconde commande à une seconde alimentation électrique distribuée installée dans un second groupe d'installations dans lequel le flux d'énergie inverse est autorisé et qui comprend une ou plusieurs installations dans lesquelles le flux d'énergie inverse est supposé.
